PEGylated chitosan protected silver nanoparticles as water-borne coating for leather with antibacterial property

Gallic acid-functionalized graphene hydrogel as adsorbent for removal of chromium (iii) and organic dye pollutants from tannery wastewater

“…[15][16][17] Indeed, tannery wastewater containing Cr(III) and organic dyes has become a serious environmental pollution, which has severely affected the sustainable development of the leather industry. [18][19][20] For the removal of both Cr(III) ions and organic dyes from tannery wastewater, adsorption has proved to be an attractive disposal technique based on its low cost, simplicity of operation and recycling of the adsorbent. [21][22][23][24] However, most traditional adsorbents, including polymeric resins, 25 activated carbon, 26 silica, 27 and metal oxides, 28,29 usually suffer from either low adsorption capacity or low efficiency.…”

Tailor-made zwitterionic polyurethane coatings: microstructure, mechanical property and their antimicrobial performance

“…Producing anti-biofouling coatings or membranes is of great interest in numerous technological applications such as water purication, 1 medical implants and devices, 2 marine antifouling, 3 food packaging, 4 textiles, 5 and leather nishing. 6 As far as the coatings for leather antifouling nishing are concerned, restrictions on the use of biocidal agents and high-risk chemicals potentially toxic to human beings have necessitated the development of environmental-friendly antimicrobial coatings. Polyurethane is one of the most favourable matrix polymers, biocompatible, biodegradable and versatile.…”

Facile fabrication of functional cellulose paper with high-capacity immobilization of Ag nanoparticles for catalytic applications for tannery wastewater

“…However, virgin AgNPs tend to aggregate in the catalytic process, thus inhibiting its catalytic performance and practical application [39]. To overcome this shortcoming, the immobilization of silver nanoparticles on a support material has been considered as an effective method to improve the stability of AgNPs, which is conducive to maintaining the catalytic ability of AgNPs [40,41].…”
